Editing HTTP 404 (section)

==Tracking 404 errors==
A number of tools exist that crawl through a website to find pages that return 404 status codes. These tools can be helpful in finding links that exist within a particular website. The limitation of these tools is that they only find links within one particular website, and ignore 404s resulting from links on other websites. As a result, these tools miss out on 83% of the 404s on websites.<ref>{{cite web|url=https://springtrax.com/key-stats-about-404-errors/default.htm#/section4|title=Sources Leading To 404s|publisher=SpringTrax|access-date=11 February 2013}}</ref> One way around this is to find 404 errors by analyzing external links.<ref>{{cite web|url=http://searchengineland.com/a-data-centric-approach-to-identifying-404-pages-worth-saving-152844|title=A Data-Centric Approach To Identifying 404 Pages Worth Saving|last=Cushing|first=Anne|date=2 April 2013|publisher=Search Engine Land|access-date=7 June 2013}}</ref>

One of the most effective ways to discover 404 errors is by using [[Google Search Console]], [[Google Analytics]] or crawling software.

Another common method is tracking traffic to 404 pages using log file analysis.<ref>{{cite web|url=http://www.404errorpages.com/#tracking|title=Tracking and Preventing 404 Errors|publisher=404errorpages.com|access-date=7 June 2013}}</ref> This can be useful to understand more about what 404s users reached on the site. Another method of tracking traffic to 404 pages is using JavaScript-based traffic tracking tools.<ref>{{cite web|url=https://springtrax.com/how-springtrax-helps/understand-your-websites-404-errors.htm|title=Understand 404 Errors|publisher=SpringTrax.com|access-date=7 June 2013}}</ref>
